Abstract:

In basis of the functional requirements of the LTE tester, the paper proposed and designed a software platform research program of LTE network tester. Combined with analysis of GTPv2 protocol, the thesis use modular method and IE list traversal algorithms for message decoding, introduce a Hash structure indexed by the key field for GTPv2 message synthesis, use a mathematical model that combine with message identifier and offset for identify of the upper packet, solve the key challenges that difficult to transmit information in decoding module, module coupling and low efficiency of CDR synthetic. Finally, the practical commercial test shows that the mentioned program in this thesis are effective.

Key words: LTE, GTPv2, message decoding, Hash
